wwww mwaa NITED STATES SAMUEL G. GOSS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE GOSS PRINTING PRESS COMPANY,

or SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 461,189, dated October 13, 1891.

Application filed June 18,1891- Serial No. 396.777. (No model.)

T all whom, it may concern:

Be it known that I, SAMUEL G. GOSS, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification, reference be ing had to the accompanying drawings, in which [0 Figure 1 is a side elevation. Fig. 2 is atop or plan View. Fig. 3 is an end elevation looking in the direction indicated by the arrow in Fig. 1.

My invention relatesto printing-presses,

I 5 and more especially to presses which are fitted with cylinders which are made in two parts and are adapted to be run at difierent rates of speed. These cylinders may be substantially as shown and described in my application filed March 5, 1890, Serial No. 342,779.

The object of my invention is to provide an improved printing-press in which two webs of paper maybe printed at the same time and in which the webs may be passed through the press and printed at different rates of speed.

Another object of my invention is to provide improved mechanism for operating the printing-press, so that the cylinders may be operated either singly or together, as desired.

0 I accomplish these objects as illustrated in the drawings and as hereinafter specified. That which I deem to be new will be pointed out in the claims.

In the drawings, 1 indicates the frame of 5 the printing-press, which may be of any suitable construction adapted to contain the different parts of the machinery.

2 indicates a bracket or frame, one of which is mounted at each side of one end of the printing-press, each bracket being provided with two sockets 3, adapted to receive the ends of mandrels 4, upon which are placed ordinary rolls of printing-paper 5.

Mounted near the top of the frame 1 of the 5 press are six cylinders 6 7 8 9 10 11, which are mounted on shafts 12, which shafts are journaled in opposite sides of the frame and extend transversely of the frame. Of these cylinders 7 and 10 are type or form cylin- 5o ders, S and 9 are impression-cylinders, and6 and 11 are ink-drums. The cylinders 7, 8,

9, and 10 are divided centrally, portions 13,- 14,15, and 16 of the cylinders being keyed to their respective shafts. The sections 17 18 19 20 of the cylinders 7 8 9 10 are loosely mounted upon the same shafts and are adapted to be locked to the other sections of the cylinders to form continuous cylinders, sub stantially as described inmy former application, Serial No. 342,779. The shafts 12, upon which are mounted the cylinders 7, S, 9, and 10, at one end are provided with gear-wheels 21, 22, 23, and 24, adapted to mesh successively with each other, substantially as shown.

in Fig. 2, so that byoperating one of the gearwheels the others will be also operated. A drive wheel or pulley 25 is mounted upon a shaft 26, suitably journaled in the frame, preferably at a point below the cylinders 7 and S, as best shown in Fig. 1. 7o

27 indicates a gear-wheel mounted upon the shaft 26, which is adapted to mesh with the gear-wheel 21 to operate the gear-Wheels 21, 22, 23, and 24..

The sections 17, 18, 19, and 20 of the 'cylinders 7, 8, 9, and 10 are provided at their outer ends with geauwheels 28, 29, 30, and 31, which are adapted to mesh with each other in a manner substantially the same as the gear-Wheels 21, 22, 23, and 24 to operate the section's 17 18 19 20 of the cylinders 7 8 9 1O when such sections are not locked to-the sections 13 14 15 16, as herei-nbefore described.

YVhen the sections of the cylinders 7, 8, 9, and 10 are not locked together and it is de-; 35 sired to operate the sections 17,18, 19, and 20 at a greater or less speed than the other sections of the cylinders, theyare operated from the drive-wheel 25 by a gear-wheel 32, which is movably mounted upon the opposite end of 9c the shaft 26 from that upon which is mounted the drive-wheel 25, as indicated by dotted lines in Fig. 2. By moving the gear-wheel 32 toward the end of the shaft it will mesh with a gear-wheel 33, which wheel is in mesh with 5 a similar wheel 34, both suitably mounted in a different rate of speed than the sections 13,

14, 15, and 16 when the sections of each cylinder are not locked together.

The ink-drums '6 and 11 may be ofany suitable construction and are adapted to be operated from the drive-wheel 25. This is accomplished byproviding each of the cylinders 6 and 11 with a gear-Wheel and 36, which gear-wheels are keyed to the shafts upon which the respective cylinders or drums are mounted. The gear-wheels 35 and 36 are operated from the shafts upon which are mounted the cylinders 7 and 10, respectively, by means of gear-wheels 37 38, which operate the gear-wheels 35 36 through intermediate gear-wheels 39 and 40. The intermediate gear-wheels 39 and 40 are preferably mounted in the side of the frame of the press in any suitable manner, as best shown in Fig. 2.

The shafts, upon which are mounted the drums 6 and 11, are also provided at their opposite ends with cog-wheels 41 and 42. The cog-wheels 41 and 42 are adapted to mesh with wheels 43 and 44, suitably journaled in the frame of the machine, as best shown in Fig.

1,whicl1 cog-wheels are adapted to mesh with similar wheels 45 and 46. Thewheel 45 isse cured to the end of a cylinder 47, which eX- tends half-way across the machine and is mounted upon a suitable shaft 48, whichis journaled in brackets 49, which are adapted to slide vertically on the frame of themachine, as best shown in Fig. 1. The brackets 49 are each provided with a slot 50, through which pass screws 51, which are adapted 'to be screwed into the frame of the machine to serve as guides for the brackets 49, and by means of which the brackets may be secured to the frame at any desired height. The

bracket which supports the inner end of the shaft 48is secured in a similar manner to an upright 52, centrally located in the machine, as best shown in Fig. 3.

53 indicates a rod, which at one end is connected to the exterior bracket 49 and at the other end .to the short arm 54 of a lever 55, which is pivoted to the frame at any suitable point.

' the upward motion of the lever 55.

56 indicates a rod connecting the two brackets 49, so that both brackets will be moved equally by the operation of the lever 55.

57 indicates a pin, which is adapted to limit The arrangement of the lever 55, connecting-rod 53,

. rod 56, and brackets 49 is such that by operating the lever the brackets 49, with the cylinder and ink-rollers mounted upon them,

type or form cylinders 7 and 10, and alsoby the rotation of the ink-cylinders 47. The ink-rollers 59 are of equal length with the sections 17 and 20 of the type or form cylinders. The object of the rollers 59 is to ink the sections 17 and 20 of the type or form cylinders when such sections are running at a different speed from the other sections of the type or form cylinders.

60 indicates vibrating ink-rollers, which united, in order to operate them at the same rate of speed the rollers 61 may be replaced by rollers which extend across the press, and will then operate in the usual manner.

indicates rollers, which are adapted to feed ink from the rollers 60 to the rollers 61. The arrangement of the rollers at each end of the press is practically the same.

63 64 indicate feed-rollers, which are of equal length with the cylinder 47 and-are mounted upon arms 65 and 66 of rock-shafts 67 and 68, which are suitably journaled in the frame of the press and are adapted to be operated by any suitable mechanism to cause the rollers 63 and 64 to vibrate between the ink-drums 6 and 11 and the cylinders upon which are mounted the wheels 45 and 46. By this construction when the surface of the ink-drums 6 and 11 is moving at a greater or less rate of speed than the Wheels 45 and 46 ink will be carried from the ink-drums to the cylinders by means of the feed-rollers 63 and 64.

69 indicates ink fountains or reservoirs, one of which is located at each end of the press, which reservoirs may be of the usual form.

70 indicates plates which are placed over the reservoirs 69,- and which are adapted, together with rollers 71, which are mounted in theink-reservoirs, to regulate the supply of ink which is supplied to the ink-drums 6 and 'Ioc tog

IIO

11. The plates 70 each extend half-way across 3 the ink-reservoir, their inner ends being supported by a bar 72 or in any other suitable manner, and are adapted to move toward or from the roller 71, so that a less or greater amount of ink may be supplied. In order to better adjust the plates 70, they are provided, preferably at each end, with adjusting-rods 73, which are operated by nuts 74, screwed upon the outer ends of the rods 73, as best I shown in Fig. 2.

When the two sections of the press are being operated at different rates "of speed, different amounts of ink will be required for the type or form cylinders. By the construction described if the sections 17 and 20 of the type or form cylinders are being operated at a slower rate of speed than the sections 13 and 16 the plate at one side of the press is so adjusted that a less supplyof ink will be furnished the rollers which inkthe cylinders 17 and20.

When it is desired to operate both sections of the cylinders at the same rate of speed, the sections 13, 14, 15, and 16 are locked to the sections 17, 18, 19, and 20, respectively, substantially as described in my former application hereinbefore referred to. The operation of the press will then be the same as in an ordinary press, except that the paper will be printed from two rolls on two webs. If desired, a single wide web may be used instead of the two webs. In the latter case some suitable slitting device may be provided. The paper will pass from the rolls 5 over rollers 75, between the type or form cylinder 7 and impression cylinder 8, thence upward be tween the impression-cylinders 8 and 9, thence downward between the impression-cylinder 9 and type-cylinder 10, and thence to any suitable folding-machine or delivery apparatus.

When the sections of the cylinders are operated at different rates of speed, the sections 17, 18, 19, and 20 are disconnected from the sections 13, 14, 15, and 16, so that they may be rotated independently of said sections. The gear-wheel 32 is then moved outward upon 'the shaft 26 until it meshes with the wheel 33.

By then operating the drive-wheel 25 the sections 13, 14, 15, and 16 will be rotated at one rate of speed and the sections 17, 18, 19, and 20 at a different rate of speed, the difference in the rapidity of rotation being determined by the difference in size between the wheels 27 and 32. The amount of the web printed will therefore vary accordingly.

If it is desired to print a newspaper having six pages, one section of the machine may be so adjusted as to operate at half the speed of the other, and therefore if the press is adapted to print four pages on either the sections 13, 14, 15, and 16 or the sections 17, 18, 19, and 20 while running independently of each other at the same rate of speed by running the sections 17 18 19 20 at half the speed of the sections 13, 14, 15, and 16 at each revolution of the sections 13, 14, 15, and 16 of the cylinders four pages will be printed, while at the same time the sections 17, 18, 19, and 20, run ning at half the speed of the other sections, will print only two pages. If it is desired to printv an eight-page paper, by locking the sections of the cylinders together and disengaging the wheel 32 from the wheel 33 the sections of the cylinders may all be run at the same rate of speed and eight pages will be printed at each revolution of the cylinders.

Ordinarily the forms are placed on the type or form cylinders so that the columns are parallel with the axes of the cylinders; but I do not confine myself to this arrangement.
